Lionsgate has released a new trailer for Jim Sheridan‘s Brothers on Yahoo. The film stars Tobey Maguire, Jake Gyllenhaal, Natalie Portman, Sam Shepard, Clifton Collins, Jr., Carey Mulligan, and Ethan Suplee. It is written David Benioff (The Kite Runner, 25th Hour). Check out the trailer below.

Plot: When a decorated Marine goes missing overseas, his black-sheep younger brother cares for his wife and children at home—with consequences that will shake the foundation of the entire family. BROTHERS tells the powerful story of two siblings, thirtysomething Captain Sam Cahill (Tobey Maguire) and younger brother Tommy Cahill (Jake Gyllenhaal), who are polar opposites. A Marine about to embark on his fourth tour of duty, Sam is a steadfast family man married to his high school sweetheart, the aptly named Grace (Natalie Portman), with whom he has two young daughters (Bailee Madison, Taylor Grace Geare). Tommy, his charismatic younger brother, is a drifter just out of jail who’s always gotten by on wit and charm. He slides easily into his role as family provocateur on his first night out of prison, at Sam’s farewell dinner with their parents, Elsie (Mare Winningham) and Hank Cahill (Sam Shepard), a retired Marine.

This trailer is ridiculous. Is it a horror film? I’m definitely intrigued.  I’m looking forward to see Carey Mulligan after her remarkable performance in An Education.  I loved David Benioff‘s work on 25th Hour and I’m looking forward to what he does with this.

Brothers hits theaters December 4th.
